operational amplifiers

An operational amplifier, or op-amp, is a versatile electronic device that amplifies small electrical signals. It takes a weak input signal and increases its strength, making it suitable for various applications like audio amplification, signal processing, and sensors. Inside, it has components that compare two input voltages and produce a proportional output. Op-amps are essential building blocks in electronic circuits, providing precise control and amplification of signals, enabling devices like microphones, speakers, and measurement instruments to function effectively. They are designed to be adaptable, stable, and easy to incorporate into complex electronic systems.
